Blekhem, Sweden wind farm facts and numbers

Blekhem wind farm is located in Kalmar County, Sweden. It was finished in 2011 and is owned by .

It is near Västervik.

See below for data.

For the most part, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or greater.

The very best location for something like Blekhem is a steady availability of non-turbulent wind. Additionally, you wouldn’t get a turbine like involved if Blekhem was not built near local demand or transmission capaVästervik.

During the planning stages the Blekhem wind farm would have been checked and endorsed through wind measurements. Meteorological wind data alone is usually not sufficient for exact siting of a large wind power project.

Site information around Västervik is a major aspect in the development choice Winds around Västervik are analysed for at least a year or so alongside the development of detailed maps. Only then are wind turbines installed.

The wind blows sooner at higher altitudes as a result of reduced effect of drag. The rise in velocity with altitude is most extraordinary near the surface and is affected by landscape, surface roughness, and upwind hurdles such as trees or buildings. Velocity grows with altitude and is more distinct near land and is changed by topography, surface and limitations.

Wind speeds growing with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, enhances the predicted wind speeds by 10%, and the anticipated power by 34%.

The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out in order that they don’t affect one another. But micrositing increases placement, specifically in hilly areas.

Individual turbines at Blekhem are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.

At a substation, this medium-voltage electric energy is improved in voltage using a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and probably access roads to every turbine site.
